1'0 all whomrit may concern:

Be 1t known that I, Gnonen HENRY VVi-Irrn, citizeiyof the UnitedStates,- resid ing at Oil City in the'county of Venango and State ofennsylvania, have invented certain new and useful Improvements in-Blanks for the Manufacture of Middle Rings for Pipe-Couplings, & c;.;and Iv do hereby declare the following .to be a full, clear, and

exact description otthe invention, such as will enable others skilled inthe art to which ,it appertains toniake and use the same.

- My invention consists in the novel features herelnafter describedreference being had to the accompanylng drawlng which illustrates oneform in which I have contemplated elnbodying iny invention and saidinvention is fully disclosed in the following description and claim.

" metal bar or blank 'adapted especially for The object of nay-Inventionis to provide a the manufacture of middle rings for rubber packed-pipecouplings: These middle rings are proyidediwitha substantially centralin- "s 'kelp, which is formed ofwrought metal as ternally projectingcentering stop and the vend portions.of the ring are provided withpacking. engaging portions which are usually bent or fiaredoutwardly toform an annular packing recess at each end of the ring.

My present invention consistsof a bar 01' wrought iron or 'steel,- andis preferably "formed by rolling. length-than breadth and of greaterbreadth The bar is of greater than thickness, and is provided .on oneface with acentral longitudinally disposed bead,

'extendingthroughout thelength of the bar v or blank, or it maybeinterrupted at inter- F 'v.als.' I prefer to have the bead extendthroughout the lengthof the bar or blank. The lateral edges of the baror blank. arc

' preferably oppositely beveled or inclined in such'a. manner that thebeveled edges if prod'uced would intersect on the same side of the bar'onwhich the head is located, or in other words the beveled edgesconverge toward the beaded face.

embodying my invention. Fig. 2 is a transside elevation of ablank orbar-suitable for lap-welding. "Fig. 4 is an. elevation ofthe fblanl; orbar shown in bent into ring fol-1n preparatory to welding. Figs. 5 and(S are sectional views of rings produced from my improved bar or blank.Fig. 7 is a see tional view of a modified form o t' bar or blank.

In Fig. 1 I have shown in perspectives piece of the skelp or bar as itcomes from the rolls. A represents the body of the bar a thelongitudinal bead, and a a the bev;

eled lateral edges converging toward the 1 beaded face, asclearlyshownin cross section in Fig. 2. \Vhen thering is to be inade byla pnvelding the bar is cut in suitable lengths by incisions inclined tothe faces of the bar and parallel to each other so that the blank isprovided with parallel inclined endffaces a a as clearly shown in Fig.3. If the rings, are to be butt-welded, however, the ends of the blanksmay be perpendicular to the faces as will be obvious.

Ill

Fig. 3 shows a completeblank suitable for in ends of the ring formed bythe beveled edges of the blank, or bar. Fig. 6 shows in section a ringwhich has had its end port1ons flared outwardly to br ng the beveledportions perpendicular to the longitudinal axis of the ring. M

Fig. 7 is a sectionalview of a modified Form of: blank or bar indicatedat A, having the central head a". and having the latoral edgesperpendicular to the broad faces,

ilistea'd of beveled. The process of treating I this blankis disclosedin my application Serial No. 295,885), filed Jan. 13, 1906.

What I claim and desire to secure by Let-v ters Patent is:- 'lhe hereindescribed blank for a middle ring for pipe couplings. consisting of abar of wrought inetalhaving a longitudinally disposedbead substantiallycentrally located on one face and hiring its lateraledges bevcledoppositely and converging-toward said beaded face.

In testimony whereof I aiiix in the presence of two witnesses.
